Popular addition to wedding dress going on (2,5)
I believe the answer is:
in train
'dress going on' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'popular addition to wedding' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'addition to' is a charade indicator (letters next to each other).
'wedding' becomes 'intra' (I can't justify this - if you can you should believe this answer much more).
'in' put after 'intra' is 'IN TRAIN'.
Can you help me to learn more?
(Other definitions for in train that I've seen before include "happening?" , "Under way" , "making progress" , "Being dealt with (going by rail!)" , "Moving forward" .)
